1. What Epistemological Resources Affect Chemistry Teachers’ Sense of "What Worked"

   Schafer, AGL; Stowe, RL. (January 2021, 2021 NARST International Meeting)

   null (Ed.)

   Teachers’ sense of “what is taking place with respect to knowledge” drives their perspective on “what works” and “what is likely to work” in their classroom context. Scholarship by Hammer, Russ and many others indicates that this “sense” is very often context-sensitive and may be productively modeled as a local coalescence of small-grained epistemological resources. Presented here is an investigation of the epistemological resources contributing to high school chemistry teachers’ framing of “what works” in their learning environment. Teacher reflections are unpacked and characterized for classroom information noticed and responded to when considering “what worked” during the 2019-2020 school year. Preliminary findings suggest epistemological resources guiding “what worked” often align with a view of knowledge as propagated stuff. Thus, implying that teachers’ reasoning about “what works” is guided by how well knowledge is transferred to students. Also present was evidence that epistemological resources aligned to views of knowledge as fabricated stuff were activated. The perspective that knowledge is inferred or developed from other knowledge, rather than passed from an authority figure, aligns well with reform efforts that emphasize student sensemaking. This study is part of a larger program in which a teacher-researcher collaborative adapts and refines evidence-based curricular materials for an undergraduate chemistry course for use in high school. These materials are structured around scaffolded progressions of big ideas (e.g., energy, electrostatic and bonding interactions) that build in complexity as students make sense of increasingly complex phenomena. Ongoing improvement of transformed materials is dependent upon the ability to initiate and stabilize a sense of “what works” consistent with sensemaking aims.

2. Teaching secondary mathematics lessons for joy and wonder

   Scheitlin, K.; Dietiker, L.; Riling, M. (October 2023, Association of Mathematics Teaching)

   As a group of teachers and researchers in the USA who have collaborated to design captivating lessons with this story perspective, we have been exploring how centring students’ aesthetic reactions in our design process can result in lessons that are more captivating (Dietiker et al., 2019). In this article, we share a lesson designed by one teacher (Kayla) in collaboration with her co-authors and colleagues. This lesson was enacted with her Year 10 students (aged 14–15) in a non-accelerated integrated mathematics course at a diverse high school in a working-class suburb.

3. "Off the bench": three case studies of Geographic Information Systems (GIS) integration in high school chemistry instruction

   Hammond, T; Brown, K; Alexander, C; Weinburgh, M; Popejoy, K; Bodzin, A; Morrison, J; Malone, D; Firestone, J; Lightner, L; et al (May 2024, Innovations in Science Teacher Education)

   Across Texas, Washington, and Pennsylvania, three university teams worked with teachers at three high schools to integrate geographic information systems (GIS) and other geospatial tools into chemistry lessons as part of a larger, multi-disciplinary teacher professional development initiative. Each university followed a specific design model of socio-environmental science investigations (SESI) in their professional development and curriculum development processes. Each teacher’s work is presented as a case with distinct school contexts, professional development experiences, classroom implementation outcomes, and reflections after implementation. Cross-case findings include variability in teachers’ adoption processes, the importance of cross-site collaboration, and the ability of geospatial tools to bring chemistry topics “off the bench” and into students’ thinking about their world. These cases present an advance in the curricular reach of GIS, which to date has not been broadly used in high school chemistry instruction. Further, the cases illustrate examples of the teachers’ geospatial science pedagogical content knowledge.

5. Small Teacher Moves with Big Impacts in Shaping Students’ Sensemaking and Intellectual Authority in Science

   Schellinger, J.; Morandi, S.; Southerland, S.A.; Jaber, L.Z.; Tekkumru-Kisa, M.; & Krishnan, H. (January 2021, National Association for Research in Science Teaching Annual Meeting 2021)

   null (Ed.)

   This study explores the epistemological framing dynamics in one middle school biology classroom and how those dynamics shape students’ collaborative sensemaking in science. We trace how the teacher’s instructional moves shaped students’ framing, and the ways in which that framing influenced students’ learning. Our analysis shows that while the teacher framed small group argumentation activities as spaces for students to generate and negotiate ideas, brief but influential moves at the end of the lesson, which emphasized the correct answer, undermined students’ sensemaking and intellectual authority. These findings have implications for the design of teacher education highlighting the need to promote teachers’ awareness of the impact of their instructional moves in terms of how students frame their efforts in the classroom.
